Brake drum and hub size for replacement

[RMOsgood2016]

Howdy,
I have a 2016 GD 313RLTS travel trailer with Lippert axles LCI52-SB-86.5 Two axles rated for 5200# each.
I cannot seem to figure out what replacement brake drum and hub assembly to order. So far my info gathering has led me to a 12" x 2", 15" wheel, 6 on 5 1/2". However when looking up ones to order it askes what the bearing or seal sizes are. The bearings are worn and show no numbers. I'm hoping GD knows what they put on this trailer. Seems overly difficult to find out what brakes were put on this axle so that they can be ordered.
Help please, Rob

There should be a label on the axle that you can scope out, and email the information on it, to Dexter or Lippert. They should be able to give you all the pertinent data about your axles.

Thanks Hoopy!
No such luck, any label that was there is long gone. It seems to only verify what axle was used, not brake components.
I've got the build sheet, VIN #, still no answers. I get close, but each time it comes down to a response similar to "there were different drums and hubs used on the same Lippert axle" for that model year. aargh!
Wouldn't really be too much of a deal except I want to purchase online for better pricing. Can't exactly 'walk' in to show someone the drum and bearings online.
The only real difference in drums seems to be the inner diameter of the seals and bearings used. I'll keep digging!

Look at Dexter Parts Online. This will give you all the part numbers for each bearing and seal.

Should be inner bearing and race 25580
outer bearing and race L67048
seal 10-36
